Definitions

  • US2011258570 A1 relates to a method for using an electronic device having a display to prepare a patient for a medical treatment, the method including the steps of: representing a world on the display, wherein one or more medical objects related to the medical treatment are placed in the world; receiving an input from the patient to select the medical objects; selecting the medical objects; and providing feedback to the patient to indicate that the medical objects have been selected.
  • imaging scan protocol refers to a set of computer executable instructions that can be provided to the scanning imaging system in order to control the scanning imaging system to perform an imaging operation in a desired manner.
  • MRI magnetic resonance imaging
  • pulse sequences are a fast-field echo sequence, turbo-field echo sequence, gradient-echo sequence, inversion Echo Single-Shot EPI Gradient Echo etc.
  • imaging scan includes both scans including only a single 2D image frame acquisition pass as well as 3D scanning techniques wherein each individual scan is performed as a time series of individual acquisition passes which are equal in terms of parameters and contrasts.
  • the term “scan” may refer to a data acquisition sequence including applying a static magnetic field and a gradient magnetic field, transmitting an RF pulse, receiving an MRI signal, storing the received MRI signal.
  • virtual reality system refers to a system which that used software to generate realistic images and sounds that replicates a real environment and simulate a user's physical presence in this environment.
  • the environment is the scanner to be used for performing the imaging scan, for example a magnetic resonance imaging scanner.
  • the simulation includes for example the movement of the patient lying on a table into the bore of the magnet of the MR scanner, as well as the situation when a region of interest of the patient is located within the bore of the scanner and is subject to an imaging scan.
  • Embodiments of the invention may have the advantage that the total quality of the imaging is increased.
  • the physiological data recorded during the simulating permits to the deduce information like for example the stress level the patient experiences during the simulated imaging scan.
  • the patient may start making undesired movements and breathe faster, which may have a negative effect on the quality of the MR images acquired during a real MR scan.
  • the straightforward compensation of low image quality would be the repetition of performing a certain part of the imaging scan or even the whole imaging scan, which would in turn stress the patient even more and additionally make the imaging system unavailable for imaging of other patients.
  • individual physiological reactions of the patient with respect to the simulated imaging scan can be considered for accordingly modifying the chosen imaging scan protocol.
  • the total quality of the imaging may be significantly increased.
  • the headset may comprise a sensor which records the actual heart rate of the patient and the breathing rate of the patient.
  • the skin conductance of the patient may be easily measured using conductivity sensors that are integrated into the headset.
  • the method is further comprising generating a 3D model of the scanner to be used for performing the imaging scan and generating an acoustic model of the noise emissions of the scanner resulting from performing the imaging scan, the simulating comprising an optical visualization of the imaging scan using the 3D model and an acoustic simulation of the imaging scan using the acoustic model, the optical visualization and the acoustic simulation mimicking the visual and acoustic impressions on the patient when the patient is subject to the imaging scan in reality.
  • the patient knows exactly what to expect and what to do during the imaging scan. For example, in case the patient has to perform some sort of breath holding technique during at the imaging scan, since he is trained accordingly by the simulation the patient knows in advance how to react to certain spoken breath holding commands that will be given to him by the operator or the imaging system itself during the real imaging scan. It has to be noted here that the provision of spoken commands to a patient can be automatically performed by the scanning imaging system. The provision of the commands via a loudspeaker or headphone the patient is wearing during the imaging may be part of the scanning imaging protocol. Again, the risk of scan delays due to wrong or the late response of the patient to certain spoken commands is minimized which in the turn increases the scanning imaging system availability to other patients.
  • the noise emissions of the scanner may be due to operations of gradient coils, pump systems used for cooling a magnet of for example the MRI system, as well as commands provided to the patient in verbally manner during the imaging scan.
  • the optical visualization of the imaging scan using the 3-D model comprises for example the movement of the patient lying on the movable bed of the scanner into the bore of the scanner.
  • the physiological data is comprising anyone of the following: blood pressure, skin conductance, heart rate, breath rate, breathing pattern, blood oxygen saturation, pupil width, pupil movement, muscle tension (EMG), neuronal activity (EEG), skin temperature, reaction time for performing a physical or mental activity, breath hold duration.
  • the method is further comprising anyone of in case a combination of values of the physiological data is above a predefined threshold level, modifying the chosen imaging scan protocol such that the combination of values of the physiological data to be expected when performing the imaging scan protocol in reality is reduced below the threshold level, in case the combination of values of the physiological data is below a predefined threshold level, modifying the chosen imaging scan protocol such that the combination of values of the physiological data level to be expected when performing the imaging scan protocol in reality is at the threshold level.
  • the chosen imaging scan protocol can be modified in such a manner that the combination of values of the physiological data is increasing but still below the threshold level.
  • certain parameters of the imaging scan protocol may be modified to increase breath hold durations or noise emissions due to higher gradient coil magnetic fields. This in turn leads either to a reduced total imaging time or to higher quality of the acquired MR images.
  • the modification of the chosen imaging scan protocol is comprising anyone of: a modification of the time duration of the chosen imaging scan protocol, a modification of the noise level resulting from performing the chosen imaging scan protocol, a modification of the image acquisition parameters of the chosen imaging scan protocol, a modification of the image reconstruction parameters of the chosen imaging scan protocol, a splitting of the chosen imaging scan protocol into a set of scan sequences separated in time from each other, rearranging the order of a set of scan sequences comprised in the chosen imaging scan protocol.
  • the imaging scan protocol may for example be adapted to the pre-recorded patient specific pattern in such a manner that images are always taken during the same phase of breathing. As a consequence, all recorded images show the same geometric conditions of the body of the patient which simplifies a high quality image reconstruction process.
  • the scanning system is a magnetic resonance imaging system.
  • other types of scanning systems like for example CT scanning systems may be used.
  • the computer readable medium may be a computer readable signal medium or a computer readable storage medium.

Such a propagated signal may take any of a variety of forms, including, but not limited to, electro-magnetic, optical, or any suitable combination thereof.
  • a computer readable signal medium may be any computer readable medium that is not a computer readable storage medium and that can communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device.
  • These computer program instructions may also be stored in a computer readable medium that can direct a computer, other programmable data processing apparatus, or other devices to function in a particular manner, such that the instructions stored in the computer readable medium produce an article of manufacture including instructions which implement the function/act specified in the flowchart and/or block diagram block or blocks.
  • a 'user interface' as used herein is an interface which allows a user or operator to interact with a computer or computer system.
  • a 'user interface' may also be referred to as a 'human interface device.

  • the magnet 104 is a superconducting cylindrical type magnet with a bore 106 through it.
  • the use of different types of magnets is also possible; for instance it is also possible to use both a split cylindrical magnet and a so called open magnet.
  • a split cylindrical magnet is similar to a standard cylindrical magnet, except that the cryostat has been split into two sections to allow access to the iso-plane of the magnet, such magnets may for instance be used in conjunction with charged particle beam therapy.
  • An open magnet has two magnet sections, one above the other with a space in-between that is large enough to receive a subject: the arrangement of the two sections area similar to that of a Helmholtz coil. Open magnets are popular, because the subject is less confined.
  • a collection of superconducting coils Inside the cryostat of the cylindrical magnet there is a collection of superconducting coils. Within the bore 106 of the cylindrical magnet 104 there is an imaging zone 108 where the magnetic field is strong and uniform enough to perform magnetic resonance imaging.
